Hi,
I am not 100% sure if I understand your issue correctly, so please
forgive me if my advice is completely bogus :)
I see two possible solutions:
a) if you need to use a getter function for file.path, then store the
path instance in an internal field of the file:
file_open(path) {
args.This()->SetInternalField(1, path);
}
b) alternatively, do *not* define a getter for file.path and simply
store the path value via Set:
file_open(path) {
args.This()->Set(v8::String::New("path"), path);
}
In the second scenario, you can easily retrieve the stored path using
args.This()->Get(v8::String::New("path")) - no getter is called, no
stack overflow happens :)
Hope this helps,
Ondrej
